Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972782, here are decompositions:

61 + 972721 = 972782
103 + 972679 = 972782
313 + 972469 = 972782
373 + 972409 = 972782
379 + 972403 = 972782
409 + 972373 = 972782
439 + 972343 = 972782
463 + 972319 = 972782

Showing the first eight; more decompositions exist.
